If that's all it is, then we actually have a chance at producing a VGA board for the NeXT machines. From looking at the rest of the board, it's mostly just memory buffers and whatnot... possible to replace with some more modern approaches even.

Sadly, no, I don't believe I do. I'll have to double check - I got that board in a lot with a few other cubes and I may just not have noticed. But by now I don't know which ones were with it, so I'll have to check all of them...

By the way, if we decide to make some sort of paddleboard that plugs into the socket instead of a complete board an a neighboring slot, those eight pads in the corner of the board supply +12 and -12v.
The seven pads immediately behind the monitor connector are all ground._________________
